. To all whom it may concern.'

Be it known that I, DAVID HoMER HAY- DEN, a citizen of the United States, anda resident of New York, county and Stateof New York, have invented certain new and Vuseful Improvements in Reinforcements for thej Composition Covering of Structural Shapes, of which the following isA a full, clear, and exact description. i

'The improvement relates to reinforcementsrfor the concrete and like composition covering of structural members and seeks to provide a simple, inexpensive reinforcement which can be transported in collapsedform and readily applied' to structural members vwith the reinforcing elements thereof in predetermined position relatively to the members. The invention consists in the features of improvement `hereinafter set forth, Iillusf tra-ted in different forms in the accompanying drawings and more particularly pointed out in the appended claims. i

' The improved reinforcement comprises a series of connected cross stays or members which are capable of expansion longitudinally of the member and of contraction laterally thereof, the reinforcementl being provided with attaching elements which hook over the anges or edges of the structural member when the reinforcement is eX- panded. The parts are so arranged that the complete engagement ofthe attaching elements with the member limit the expansion cross Vsections illustrating further modificaand the portions of the reinforcement which y are embedded in the concrete or like composltion covering are held 1n proper offset relat-ion from the structural member.

`reinforcing elements project outwardly from the base flange of the I-beam, while other portions extend downwardly and inwardly belowthe same.

This'forni of the inventionZ is preferably constructed of a length of annealed. .wire which is bent back and forth upon itself to form the series of cross sta-ys 10. `A poi-'tion of the length of wire between each pair of cross stays is .bent to `form the loop shaped'or double hook 11 and the triangular reinforcing element or loop 12, the wire being then twisted or turned one or more timesabou-t the bend of the hook,'as\indicated at 14, andl the turns or coils 14 serve to directly connect the cross stays 10. The

-attaching 'and' reinforcing elements 11 and l2aire1v thus formed of integral portions of the `cross stays which extend nbeyond the points- 'of cennectionthereof. `By reason of this arrangement theex Jansion of the cross staysv will not distort the attaching andreinforcingelements. l Y

The reinforcement is proportioned to properly tupon' af structural member of definite shape and size.` Beforeit is applied thereto, theseries of cross stays 10 are-substantial'ly parallel to one another, as shown at the lowerportion of Fig. 2. In this unexpanded condition, the space between the attaching hooks 11 at'opposite sides of the freinforcement is such that they may be readily slipped over the flanges of the structural 'member `to which the: reinforcement is to be applied. The reinforcement is then expanded andthe hooksare drawn together snugly into engagement with the flanges of the I-beam or other member and the crossstays aref separated a'nd then extend back and forth in zig-zag fashion between the attaching hooks 11 and overV the face of the' -""m'em ber.' 'In the form shown in Figs. 1,2

and 35' the Ic'ross stays are arranged to lie against the' lower face ofthe l-beam 13 and they complete engagement of the hooks 11` and tliefcross'stays 10`with the edges and *bute-rl faceofthe member will limit the "determi'ned. The reinforcing elements or' amount of expansion to thereby properly hold the reinforcing elements '12` in offset position, and s'o-that the number of reinforcing elements-per lineal foot can be preloops 12 are' arranged inplanes substantially at'right anglesto the plane of the series crossstays and-tothe face of the-"member with which'. the cross staysr engage. The re# in'forcingloops'lQ project `laterally beyond thel` edges7 of the base of ythe -I-beam and downwardly and inwardly below the same soas toiproperly reinforce the concrete covering/15 within whiclr'they are emtheform shown in` Fig. 4, the adjacent cross stays 10 are connected by twisting' adjacentV portions ofthe length of wire to# ge'tlier", asi'ndi'cated at 1G, and a portion of the wire beyond eachtwist is formed into a singlet' loop `arranged in a plane substantially at right angles to the plane of the series of "cro-ss, 4"stays andl having portions "offset both aboveandbelow the cross stays. The inner portion of the loop above the stays is shaped to forman attachinghoek` 1-1-1 for engaging the flange of the structural member, while the remainder of the loop is shaped. to form a curved reinforcingelement 12awhich'extendsabouttlie-edge of the structural member and inwardly below the same to prop erly reinforce the concrete covering 15 within which it is embedded.

The reinforcements shown in Figs. 5 and 6 are also `formed of-lengths offwire *inl which the stays are connected by twists 16,

and. in these formsV looped portions b'eyond the twists are offset above theplane ofl the cross stays. In vthe form shown in Fig. 5, a portion of each loop is doubled' upoir"itself` and shaped toform a aw, which is adapted to embrace the edgeof the flange ofltheI` beam, whilethe remainder off the loop comprises a laterally and outwardly-projecting reinforcing element 12?. The attaching jaw comprises an inturned hook 1lb1 arranged to engage the innen face of the flange of the I-beam and an "inwardly projecting lugV or e spacing element 17 arranged Vto engage the outerface ofthe I'-bea1n. In this form, the expansion is limited bythe complete engagement of the attaching and spacing elements 11b and 17 with the base' lflange of the I- beaml andthe cross stays 10` arev held offset from the outer face ofthebeam to reinforcethe concrete covering 152 The' formshown in Fig. Gis quite similar structed from aV piece of expanded metal having alternatelong and short slits aand b extending inwardly on Vopposite sides- Y V115 thereof to thereby'form the expansible series of cross stays 10( which are connected at the points `0 V'and provided with extensions CZ and e. Y Thel extensions d] are Vpreferably shorter than the extensions e and areupwa-rdly and inwardly offset, as shown in Fig. 7, 'to form attaching hooks 11d. The extensions e extend laterally from the points c and are then bent downwardly randinwardly to form reinforcing elements 12d.

'Theformshowni in Figs. 10, llf and 12 is formed ofz acontinuous length of wire, but

in this form the cross stays or members QO project laterally beyond the extensions which formvv the attachingliools and spacers. In constructing this form, each `of the cross stays is Adoubled upon itself at a point adjacent but spaced apartfrom oneendf of the stay and bent to form a laterally projecting extension 21'1having'jaw portions, an attaching hook 22 and aspacing lug 23. `The two members of the `part 21 lare secured or twisted .together adjacent the cross stay 20, as indicated at 2,4. J j 1 The formsliown in Figs. 13 and u14 comprises two series'ofcross stays `similar to that shown in igs. 10, 11 and 12, except that the attaching hooks and spacers on one side of each. series are `omitted and the corners or angles between the cross Astays at one series are connectedon one side to the corresponding corners or angles ofthe other series of cross stays. This connection is preferably formed'by-weldingthetwo series of cross stays togetherratthe'points 25. `Il: desired, the connections )may be strengthened `by small reinforcing clips V26 welded-in-position.

The form shown inV Figs. 15 `,and 16 is adapted for use upon 'an `angle bar and comprises two series of-cross stays which are similar to that shown in Fig. 4, except that the loop extensions on one side ofi` each series are omitted andthe two series 'interlocked lor` woven together, as shown. The formwshown in Fig. 17 is also similar to that shownin Fig. 4, but is modilied so that it may be appliedto a channel ban Inv this forni the loops on one side of the reinforcement are divided and one partv`oieach divided'loop isA extended upwardly to form-an attaching' hook 27 which is adapted to extend over and engage the edge of Vthev upper flange ofthe` channel beam. The other part' of. the loop: is bent downwardly and then upwardly to form a spacing element 28 which engages the `lower part of the VVer'ticalsideface ofthe channel.

In the form shown iii-Figs.. 1S and'19, the

cross stays `29 are pivotally connected` at` their ends. `Each stayis formeduof a separate-pieceofwire and at one end isbent `to form arvertical part 30,ahook 31 and a loopedreinforcing part 32, the end of which is hooked over the cross stay `at apointintermediate its ends. The opposite end of the j cross stay is provided with an eye 33 through which` the vertical portion 30 of the next adjacent-stay extendsy The parts y30 and 33H thus form a seriesoffpivotal connections between the: cross stays or links. In other respects the construction i'sfsimilar to that shown inFig. A4. `In the other forms shown, the expansion ofthe reinforcement necessarily bends the metal portions of the cross stayszat theirI vpoints i of connection, whereas in the formV shown in Figs. 18 and 19, there is.v nosuch bending,"hence,` the galvanizing coat, which is some times applied to concrete reinforcementsl to prevent corrosion, will not'be injured-- `Theform shown in Figs..v 20 and 21 is :appliedto acolumn or girder built up of `channel, irons `34 and plates 35. In this form, the Vreinforcement is made of separate pieces of wire, each forming one of the cross stays 36. The end o'each wire is bent laterally and upwardly to'form a reinforcingloop`37. The parallel adjacent ends of the loop are welded or otherwise suitably secured to the end portion 38 of the vnext adjacent cross stay. The inner side of each loop is bent to form a U- shaped hook 3S which extends about the flanges of the column or girder and acts both as an attaching hook and a spacer for securing the reinforcement in place and holding the reinforcing parts in proper oifset rel-ation.

The form shown in Figs.` 26 to 30, inclusive, is made of separate pieces of wire or end cross stays 39. The ends of the adjacent cross stays are secured together preferably by welding small clips `40 thereto. The ends of the wires which form the stays extend beyond the points of connection, one extension ofeach wire being bent laterally and then inwardly to form an attaching hook 41 which hooks over the flange of the I-beam or other structural shape and terminates in an outturned lug 42. The other extension of each cross stay is -bent outwardly and upwardly and thence inwardly to engage the face of the structural member and thus form ia spacing member 43. The extension or member 43 also projects well beyond. the edge of the beam and aids in reinforcingrthe concrete. j

The forni shownin Fig. 29 is similar to that shown in Figs. 26, 27 and 28, except that the cross stays 39 are bent so that the construction may be applied to an angle bar 19. The form shownin Fig. 30 is also similar, except that the attaching hooks 41 and spacers 43 ononeside are suitably shaped to engage the upper liange and lower inner edge` portions, respectively, of a channel iron 19.

In the form shown in Figs. 31 and 32 the stays 44 are each Jformed of a separate piece of wire and the alternate staysof the series are oppositely inclined. The lower or outer end of each stay is provided with an upwardly and inwardly bent extension forming an attaching hook45. The opposite en'dwof each stay is twisted around the attaching element or hook 45 of the next adjacentstay, `as indicated at 46, and terminates in an outwardly projecting. extension 47. If desired, the Vertical portions ol?V the attaching elements 45 of one stay and the twisted portion 46 of the next adjacent stay may form pivotal connections between the stays. As'stated, in this form, the adjacent stays of the series are oppositelyinclined with respectto the face of the `structural member. The upper or inner end of each stay engages the outer face of the member and; acts as a spacer tol hold the reinforcing portions, which are embedded in the concrete, infproper offset relation.-

The form shown in Figs. 33, 34: and 35 is especially adapted for use with a T-iron 48. Each cross stay 4:9 is formed of. a separate piece of wire and isv welded or otherwise suitably secured tothe end portion 50 of the next adjacent stay. Each cross stay is provided with an integral portion extending beyond the point of connection 50 and its extension 51 is bent laterally from the series of stays and its upper end shaped into a. semi-circular hook 52 which.- is adapted tok extend over the side edges of the base fiange of the T-iron. A series ofcross stays themselves engage ythe lower edge of the leg of the \`T-iron, as shown. It should be noted that this form is quite similar to theform shown in Figs. 26, 27 and 28,-ex cept that the spacersare omitted, since not required. The form shown in Fig. 27 is similar to the form shown in Fig. 33, except that the extensions 51 are curved upwardly and outwardly and the ends are formed into Ushaped hooks 52 which embrace the edges ofthe lowerflange of anI-beam.

The formV shown in Fig. 36 is similar to that shown in Fig. 30. The concrete covering 53 which is securely reinforced, Y is shaped to support the tile block 54.1 of a floor construction.

Vhere the'` concrete covering is securely held upon the soflit of a structural memberV by the improved reinforcement, hangers for hanging pipes and the like may be readily suspended therefrom. One form of such a hanger is shown in Figs. 22 and 23, and comprises a U-shaped member 55, the ends of which are bent into hooks 5G' and arranged to engage the Iiange of the I-beam. The hanger extends downwardly through the concrete covering andthe reinforcement thereof prevents the rupture of the covering, so that the hanger 55 is rigidly secured' ing elements or hooks or disengage the latter from the structural members. In all forms, means are provided for holding the reinforcing portions, which are embedded in the concrete, in proper offset relation.
